摘要
操动机构的运动速度是影响断路器开断性能的主要因素之一。为了精确检测操动机构的运动速度,基于LabVIEW提出一种图像处理方法,设计一套实时检测操动机构运动速度的软、硬件系统。以高速相机采集的操动机构运动图像为基础,通过LabVIEW中的图像处理模块对运动图像进行预处理,采用Laplacian边缘检测算子进行边缘检测进而提取边缘信息,并对提取的边缘信息进行直线拟合和数据处理。实验结果表明,该检测系统能够有效检测出操动机构的运动状态,实现操动机构运动状态的实时检测,为断路器运动特性检测提供技术支持。
The movement speed of the operating mechanism is one of the main factors affecting the breaking performance of the circuit breaker.To accurately detect the movement speed,this paper proposes an image processing method based on LabVIEW virtual instrument and designs a set of software and hardware systems for real-time movement speed detection of the operating mechanism.On the basis of the movement images of the operating mechanism collected by the high-speed camera,it uses the image processing module in LabVIEW to pre-process the images.The paper adopts the Laplacian edge detection operators to detect the edges and extract the edge feature information for straight line fitting and data processing.The experimental results show that the detection system can effectively detect the motion state of the operating mechanism,realize the real-time detection of the motion state of the operating mechanism,and provide technical support for the detection of the motion characteristics of the circuit breaker.
